Formats arg
for the logger
If arg
is an Exception
, it will format the error message and the back trace.
If arg
responds to to_str, it will return it.
Otherwise it will return arg
.inspect.
Updates the database with multiple values from the specified object. Takes any object which implements the each_pair
method, including Hash
and DBM
objects.
Returns self
.
Returns true
if stat terminated because of an uncaught signal.
Returns the least significant eight bits of the return code of stat. Only available if exited?
is true
.
fork { } #=> 26572 Process.wait #=> 26572 $?.exited? #=> true $?.exitstatus #=> 0 fork { exit 99 } #=> 26573 Process.wait #=> 26573 $?.exited? #=> true $?.exitstatus #=> 99
Returns the length of the queue.
Wakes up the first thread in line waiting for this lock.
Returns the replacement string.
ec = Encoding::Converter.new("euc-jp", "us-ascii") p ec.replacement #=> "?" ec = Encoding::Converter.new("euc-jp", "utf-8") p ec.replacement #=> "\uFFFD"
Sets the replacement string.
ec = Encoding::Converter.new("utf-8", "us-ascii", :undef => :replace) ec.replacement = "<undef>" p ec.convert("a \u3042 b") #=> "a <undef> b"
Updates the digest using a given string and returns self.
The update() method and the left-shift operator are overridden by each implementation subclass. (One should be an alias for the other)
Returns digest_obj.digest_length().
Construct a new class given a C:
class klass
(CUnion
, CStruct
, or other that provide an entity_class)
types
(Fiddle::TYPE_INT, Fiddle::TYPE_SIZE_T, etc., see the C types constants)
corresponding members
Fiddle::Importer#struct
and Fiddle::Importer#union
wrap this functionality in an easy-to-use manner.
Example:
require 'fiddle/struct' require 'fiddle/cparser' include Fiddle::CParser types, members = parse_struct_signature(['int i','char c']) MyStruct = Fiddle::CStructBuilder.create(Fiddle::CUnion, types, members) obj = MyStruct.allocate

Similar to read, but raises EOFError
at end of string instead of returning nil
, as well as IO#sysread
does.
Reads at most maxlen
bytes from the stream. If buf
is provided it must reference a string which will receive the data.
See IO#readpartial
for full details.
Return true if the PRNG has been seeded with enough data, false otherwise.
The current status of GC
profile mode.
Starts the GC
profiler.
Escape only the tags of certain HTML elements in string
.
Takes an element or elements or array of elements. Each element is specified by the name of the element, without angle brackets. This matches both the start and the end tag of that element. The attribute list of the open tag will also be escaped (for instance, the double-quotes surrounding attribute values).
print CGI::escapeElement('<BR><A HREF="url"></A>', "A", "IMG") # "<BR><A HREF="url"></A>" print CGI::escapeElement('<BR><A HREF="url"></A>', ["A", "IMG"]) # "<BR><A HREF="url"></A>"
Undo escaping such as that done by CGI::escapeElement()
print CGI::unescapeElement( CGI::escapeHTML('<BR><A HREF="url"></A>'), "A", "IMG") # "<BR><A HREF="url"></A>" print CGI::unescapeElement( CGI::escapeHTML('<BR><A HREF="url"></A>'), ["A", "IMG"]) # "<BR><A HREF="url"></A>"
Returns whether the form contained multipart/form-data
